Zcatalog q: howto do a NOT?
by Jos Yule 12 Nov '99

12 Nov '99

I've got a ZClass which is catalog aware object. Its got a Property which is a 'list'. I want to do a ZCatalog search on this property, excluding all Objects which have a certain value some where in the list property... How the heck do i do this? How do i do a plain <dtml-if "myObject.myPropertyList != 'aValueIDontwant'"> ? I can't figure out the proper DTML syntax... Thanks again!!! j

Best way to do access logging?
by Andrew Wilcox 12 Nov '99

12 Nov '99

I'm interested in doing some access logging for my Zope site -- a record that such and such an authenticated user accessed such and such a page. Anybody have an access log product already? Where is the best place to hook into the page serving process to grab the user name and URL when a page gets served? Any issues with storing the log in the ZODB? I can send it out to a SQL database if necessary, but would prefer to keep it within Zope (and more portable) unless there is a good reason not to. Thanks! Andrew

Zope 2.1.0 beta 1 caution - please read
by Brian Lloyd 11 Nov '99

11 Nov '99

Hi all - We (DC) have run across a bug in the 2.1.0 beta that has given us some grief on the zope.org site, and I wanted to post a caution to those folks currently using the beta. In short, if you are doing any ZClass development where your ZClasses are based on Python base classes that are still in development (e.g. you are updating the Python base classes at times), there is a risk of getting a non- unpicklable object stuck into your object database. While the sequence of events required to cause this is pretty arcane, it can potentially be a real pain to recover from. So, if you are doing active ZClass development in 2.1.0b1 we strongly suggest that you either go back to 2.0.1 or take a break until tomorrow or Monday (I hope to have a 2.1.0 b2 ready that resolves this by then). If this is too painful (or you're hardheaded or just like living on the edge :) at least be sure to back up your Data.fs regularly just in case.

Hi Hannu, Thanks for this information. I didn't notice it was ASCII char value in octal form. Cheers.

According to the wonderful platform.py the system is 'OSF1-V4.0-alpha-alpha'. The exact error is: Stack overflow: pid 26669, proc python, addr 0x140889ff8, pc 0x120049ef0 Python runs fine on normal stuff, although I haven't tested the threading stuff. Is there a simple test for threading alone (python make test works for threads)? I have in the meantime compiled the extensions without optimization, which does not change anything. Is it ok to assume that one can conclude from the fact that zope runs under redhat there are no inherent problems with 64 bit machines? Something more suspicious. I can't lookup documents past the initial screen over http but can do this over ftp. Can one assume that the ZODB subsystem is working, can I test this in other ways? Thanks nevertheless, __Janko

I didn't know that Red-hat has a RPM for the version 2 of Zope, where is it?? Anyway I think that it can not works directly out of the Red-hat instalation because of the fact that pyhton with red-hat 6.0 is version 1.5.10 whithout thread. So you have to recompile or reinstall python. For Zope itself, a lot of things works on 64bits, ZODB ,DA , ftp access, http,etc.. The only2 problems I have seen is the failure during a posting of article in confera/sqhisdot: ############################################ Zope Error Zope has encountered an error while publishing this resource.

You aren't trying to call it from another External Method by any chance, are you? Can you post the code/dtml that you are actually using to call the helloWorld method?

I'm using a DTML Document:  <h2></h2> <p> This is the  Document. </p> <p><dtml-var "helloWorld(REQUEST)"></p>  and it is generating the error I described. On the other hand if I use: <dtml-var "helloWorld(this(),REQUEST)"> instead of: <dtml-var "helloWorld(REQUEST)"> (as recommended by sergey2b(a)mail.ru in a previous post - thanks by the way ...) all work perfectly. -- Emmanuel
